Scientists have been trying for quite a long time to find a new source of increasing the body's performance, which would have no side effects and, if possible, would be natural. Such studies were conducted by Swedish specialists, who finally managed to find a natural source of stimulating brain activity.
During their research, scientists determined that illuminating a workplace with blue light helps improve brain function. To participate in the experiment, specialists selected volunteers who were divided into two groups. In the first group, a cup of coffee was used as a stimulant, while in the second, the participants' workplaces were illuminated with blue light. Both groups completed test tasks, and as a result, the second group (in which the workplace was illuminated with blue light) completed their tasks faster and better than the volunteer from the "coffee" group. Blue light helped the participants stay focused and alert longer, and their reaction speed and concentration on tasks were significantly higher. In addition, scientists noted that the group in which blue light was used, the results of test tasks were better for people with blue and blue eyes.
At present, experts do not have a definite answer as to how exactly blue light promotes brain activity. This phenomenon remains undisclosed. But experts from a Swiss university recommend that anyone who wants to perk up during or after a hard day at work use blue lighting. Moreover, experts noted that the combination of coffee and blue light has a stronger effect.
Scientists assume that blue light activates brain activity due to photopigments that are located in the human eye and transmit data about the time of day or season to the brain. These photopigments perceive blue light as daylight, so the brain receives signals of wakefulness. This discovery is especially important for professions that require responsibility at any time of day.
Previously, experts concluded that yogurt with prebiotics has a positive effect on the active work of the brain. Scientists assume that there is a direct connection between brain activity and the state of the intestines. The study examined a special yogurt that was saturated with prebiotics. According to the results of the study, in a group of volunteers who daily consumed a fermented milk product saturated with prebiotics, the reaction to various external stimuli was lower, while the participants in the experiment demonstrated a higher level of emotional calmness compared to the control group. In addition, among the participants in the study who consumed yogurt without the addition of prebiotics, experts noted mixed results. This study showed a real relationship between intestinal microflora and brain performance, which once again confirms that yogurt saturated with prebiotics has a good effect on the entire body.
